|Researchers from Murdoch University believe a recently documented method of|
fishing may be spreading throughout a population of dolphins.
Indo-Pacific bottlenose dolphins (Tursiops aduncus) in Shark Bay were
photographed engaging in 'conching' in 2007 and 2009.
The dolphins would trap small fish in large conch shells with their rostrums (beaks), then bring the
shells to the surface and shake them, causing the water to drain out and the fish to fall into their mouths. (via)
